The object of the presentinvention is to provide an electrically operated clock having minute, hour and day, indicatingdevlces, the actuating means for such devices being of a novel character, one of the primary ObJBClZS of-the :inven-tionbeing to provide day indicating devices which are ore-arranged; for further ad ust-f operation for a year without ment or attention. i i

The invention will be d'escribedwith reference to the accompanying drawings in Which- V Figure 1 1s-a view of a clock in elevation constructed'in accordance with the invention Figure 2 is asectional side elevation on the line 22, F ig. 1, theview being enlarged and the line -66, Fig. 5, looking in the direction of the arrow;

Figure 7 is a perspective view looking toward the frontof the clock casing and showing a fragment of the casing at that point surrounding the day indicating window, and the card changing mechanism adjacent the same; 7 y "Figure 8 isa plan view of the card actuator plate. i V

Carried at the centre of the clock casing A is'a dial 1 bearing the numerals 1 to 12, a minute hand 2, and an hour hand 3 being placed adjacent the dial. The minute hand 2 is carried on a tubular shaft 4,'which shaft carries a pinion 5. Hour hand 3 is carried by a shaft 6 which in turn carries a pinion -7 engaged by a second pinion 8 of like size, the latter being on a shaft 9, which carries a pinion 10 in mesh with pinion 5. For each twelve rotations of pinion 5 a single rotation of pinions 10, 8 and 7 is effected. On boss 11 is loosly mounted the sleeve 12 of arm 13, which arm carries a pawl 14:. The shaft 15 of pawl 14: is embraced by the walls of a longi tudinal slot formed in a link 16 carried at the upper end of reciprocating lever 17; Lever 17 carries a solenoid core. 18, the lefthand end of which entersa solenoid field 19, the right hand end of which enters a solenoid field 19 lVhen arm 17 ismoved to the left by solenoid 19, link 16 imparts a push to pawl 14 and the pawl gives a movement to ratchet wheel 14* which is fixed to pinion 5. At the end of such actuating movement a suitable switch device B energizes solenoid 19 and the solenoid .core 18 ismoved to the right, such movement causing link 16 to retract pawl 14: preparatory to another positive actuation of ratchet wheel 14?. A switch device B is used to close the current through solenoid field 19 when the arm17 is moved to the left. A latch pawl20 controlled byqa pull-wire 21 may engage the ratchet wheel. The pullwire 21 may also be connected to pawl 14: so as to retract the same from the ratchet wheel.

Shaft9 carries a pinion 22in mesh with a gear wheel 23, the latter being twice the'size of pinion'22 and carrying a stud 24'. The relation between pinion 22 and gear wheel 23 is suchthat the latter is given a complete rotation each twenty four hours. In such rotation stud 24 actuatesmeans forreplacing the day card at window act the casing with a new day card. i t

The relative sizes of the gears in the draw ings are merely diagrammatically shown and in practice they will be constructed to correspond with the ratios ascribed to them above. l/Vindow a, has immediately at the rear thereof a card chamber 25 in which are initially placed 365 thin cards,-each bearing the indicia for a specific day of the year. .At the rear these'cards are engaged by a puslrplate 26, the puslrplate being engaged by a cable 27 led over a pulley 28 and thence extending to a springdrum 29', the winding mechanism having the usual ratchet and pawl 30, 81. Drum 29ten ds to move in the direction of the arrow 32, Fig. 5, and therefore imparts a constant but lightpull upon cable 27 tending to move the cardstoward window 0;.

Referring to Fig. tit will be seen that to the right ofchamber 2-5 is areceptionchamber 33 for cards which-havexbeen ejected-from shoulder 36 against which the foremost card of chamber is positioned by push-plate 26.

The front card of receiving chamber 33 rests against portion 35 of the actuator plate when the parts are in the position illustrated in Figures. 4 and 8. Referring to Fig. .4 it

will be seen'that .whenyejector plate 35 is,

' given a movement to the right, of the proper length, the foremost card of chamber 25, engaged by shoulder 36*, will be ejected from chamber 25 and carried to chamber 33. In such movement the card is'carried into position to be engaged by alight spring 37 carried by the inner wall of casing A, the spring pushing the ejected card back into. chamber 33 against the light resistance of plate 34.v

WVhen a reverse or left hand movement is given to. actuator plate 35, portion 35 retracts spring 37 and closes chamber 33. A light spring 38 is employed to restore the actuator plate after an operative movement thereof, this spring being attached to a lug 39 on the actuator. plate and .to a pin 40 carried by bracket arm 41, which arm lies adjacent gear wheel23. Towardthe end of each twenty 'four hours stud 24 on gear wheel 23 strikes a cam lever 42 which is shown in detail in Fig. 7. The result is that the cam lever is swung on a pivot 43 and moved to the left from its position in said figure. The lower end of cam lever 42 carries a stud 44 which enters the walls of a slot 45 formed in actuator plate 35, causing it to bodily move to the left and thereby carry with it the foremost of the 1 cards in chamber 25. In. such manner shoulder 36 of the actuator plate will engage the edge of the card (see Fig. 4), and when 7 section 35? of the actuator plate passes to the right of spring 37, the spring will engage the card being ejected from chamber 25, and will move that card back, along with the cards in chamber 33. When spring 38 restores actuator plate 35, at a time when pin 24 has passed beyond the range of cam lever 42, spring 37 will be retracted by section 35 of the actuator plate, and the plate will come into'position so that the light'pressure of shaft or shafts supported by the opposed walls 46, the walls 46 supporting bearing bosses 46 for such purpose. The division walls for chamber 25 are indicated by the numerals 47 47 Having described my invention, what I claim and desire to secure by Letters Patent is as follows, it being understood that various modifications may be made in the form and arrangement of the elements disclosed in an embodiment shown in the drawings, without departing from the spirit of the invention.

1. In a calendar card exhibiting device, opposed solenoids,-a double core member adapt ed to coast with said solenoids, an arm carried by said core member, a ratchet wheel, a pawl actuated bysaid arm and engaging the ratchet wheel, a wheel driven by said ratchet wheel and adapted for rotation each twenty four hours, an actuating member on said wheel, a plurality of cards each bearing time indicia, an actuator plate for successively en gaging said cards and moving them from one position to another, and an operative con-- nection between said first named actuating member and actuator plate.

2. In a calendar card exhibiting device, a solenoid, a lever adapted to be actuated by said solenoid, parallel chambers, a plurality of cards each heating time indicia and disposed in one of said chambers, an actuator plate for successively engaging said cards and moving them from the first to the second chamber, a plurality of timing wheels, a ratchet and pawl connection intermediate the first named lever and said timing wheels and an operative connection between said timing wheels and the actuator plate.

3. In a device constructed in accordance with claim 2, a slidable support for each I vice is released for engagement with a;card,

ejected by the actuator plate from the first chamber, whereby said first'card is given a movement within'the second chamber.

In testimony whereof, I have slgned my name to this specification.

member 26 upon the rearmost cards of chamber 25 will result in carrying the foremost card into the recess bounded by shoulder 36 for further action.

It will be noted that two spring drums 29 are employed for member 26 (Fig. 4), although a single member would suffice in most cases. The said drums maybe carriedon a ion
